Turbidity sensors is the use of optics , through the liquid solution and scattering rate of transmittance integrated to determine the turbidity case , since the amount of haze value is gradual , usually detected in a dynamic environment , the turbidity sensor acquisition value , the need for external control for AD conversion , the conversion to obtain the corresponding environment turbidity situation, so that the sensor can also need to produce a peripheral circuit detected in the system , with a waterproof probe , mainly used in washing machines, dishwashers and other equipment turbidity testing can also be used on electronic design, graduate design, electronic competition experiments and other applications.

This Platinum thermal resistance probe is an accurate, sensitive, and stable temperature sensor with a large operating temperature range. The sensor has a stainless steal cased ceramic body which contains a small platinum thermal resistance wire allowing for temperatures to be measured between -200 and 420oC. The WZP serial has a small structure, wide range, good reliability, and short thermal response time. PTR sensors opperate by varying there resistance as a function of temperature with a close to linear relationship and minimal deviation. With low self heating the probe allows for a maximum of 5mA current resulting in a rise of not more than 0.3oC

Features:The item is for Arduino robot kit, raindrops, rain sensor, monitoring can be used for a variety of weather conditions, and converted into the number of the reference signal and the AO output.

Product description:1. The sensor uses the FR-04 high-quality double-sided materials, King Size 5.0 * 4.0CM, and with the surface of the nickel plating treatment, against oxidative, conductivity, superior performance and longevity;2. The comparator output, the signal is clean, waveform, driving ability over 15mA;3. Distribution bit to adjust sensitivity;4. Operating voltage 3.3V-5V5. The output in the form: digital switching outputs (0 and 1) and analog AO voltage output;6. A fixed bolt hole for easy installation7. Voltage: 5V8. Power indicator, the output signal LED indicator.9. TTL-level output, TTL output valid signal is low. Driving capability 100MA so, can directly drive relays, buzzer, a small fan, and so on.10. Sensitivity can be adjusted via potentiometer11. LED lights up when there is no rain output is high, raindrop up, the output ground level, LED light.12. Raindrops and control panels are separate, easy to wire leads.13. A large area of ​​rain board, more conducive to detect rain.14. Board with positioning holes to facilitate installation15. Small board PCB size: 3.2cm x 1.4cm16. Wide voltage LM393 comparator

How to use:Connected to 5V power supply, the power indicator light, sensor board is not water droplets, DO output is high, the switch lights off, dropping on a drop of water, DO output is low, the indicator light switch,Brush off the the above water droplets, has returned to output high state. . . .AO analog output can be connected to the microcontroller AD port to detect the size of the drops in the above rainfall.DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain.
